6/24/19 -- The Cal Fire Mendocino Unit has suspended debris burning in areas of Mendocino County that are in the state responsibility area. Other areas of the county are on a fire department by department basis, and some departments have already suspended burning.
Cal Fire has some exemptions to the suspension, with a special permit, outlined here, "The department may issue restricted temporary burning permits if there is an essential reason due to public health and safety. Agriculture, land management, fire training, and other industrial-type burning may proceed if a CAL FIRE official inspects the burn site and issues a special permit."
